Osteomyelitis is an infection of the bone. It can be caused by a variety of microbial agents (most common in staphylococcus aureus) and situations, including: An open injury to the bone, such as an open fracture with the bone ends piercing the skin. An infection from elsewhere in the body, such as pneumonia or a urinary tract infection that has spread to the bone through the blood (bacteremia, sepsis).
Overall, 58.9% of eligible patients were men and the average age was 69.2 years. The estimated incidence of VO increased from 5.3/100 000 population per year in 2007 to 7.4/100 000 population per year in 2010. In-hospital mortality was 6%. There was a linear trend between higher rates of in-hospital mortality and greater age. A higher rate of in-hospital mortality was significantly associated with haemodialysis use (ORs, 10.56 (95% CI 8.12 to 13.74)), diabetes (2.37 (1.89 to 2.98)), liver cirrhosis (2.63 (1.49 to 4.63)), malignancy (2.68, (2.10 to 3.42)) and infective endocarditis (3.19 (1.80 to 5.65)).
